HYDRAULIC HOSE REQUIREMENTS
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified nonconductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near
electrical conductors.
Fabric-braided (not certified or labeled non-conductive) — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certified non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydraulic
Tools. DO NOT REMOVE THESE TAGS.
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be
obtained from your Stanley Distributor.

OPERATION
CONTROLS
This unit is equipped with an advanced proportional engine control system. It provides a means of controlling
engine speed by adjusting the fuel control lever with an
actuator. The Power Unit provides two 5 gpm/19 lpm up
to 2000 psi/140 bar circuits or one 10 gpm/37.8 lpm up
to 2000 psi/140 bar circuit.

Figure 3. Panel Control Valve
Two 5 gpm hydraulic tools can be connected to the tool
circuit or one 10 gpm tool. The circuit is activated by
turning one or both flow selector switches to 5 or both
switches to 10 gpm. If both are at 10 gpm, 10 gpm can
be had by connecting to either coupler set.
the operator has selected with the flow selector switch.
When a tool is not being used the engine will not return
to idle until either the flow selector switch is turned to
the off position or the throttle control switch is turned to
auto-on.
Note: It may be necessary to reset the Controller.
At times it may be neccessary to reset the controller.
This could happen if a fault occurs in the controller. For
example, excessive engine speed. If a fault does occur
the power unit will return to an idle and the operator will
have no control of the unit. To reset the controller, simply
turn off the power unit and restart it.
USING THE 12 VOLT DC OUTLET
A 12 VDC outlet is on specific models. The DC outlet is
ON at all times.
IMPORTANT
The accessories (if left on) that are plugged
into this outlet could drain the battery.
THROTTLE CONTROL
The throttle control permits the operator to select one
of 2 operating modes after the engine has warmed up.
When starting the engine, make sure the flow selector
switch is in the OFF position. The throttle control switch
can be set in either the AUTO-IDLE-ON or AUTO-IDLEOFF positions.
STARTUP
AUTO-ON
Pull choke knob out and move the Throttle Control
Switch to the auto-idle-off or the auto-idle-on position,
whichever mode of operation the operator prefers. Ensure the flow selector switch is in the OFF position.
When the throttle control switch is in the "AUTO-ON"
position, the oil flow is regulated automatically when the
trigger on the tool activated. When the tool is not being
used the engine will return to idle automatically, after a
10 second delay.
This setting will produce one or two 5 gpm/19 lpm circuits or one 10 gpm/37.8 lpm circuit depending on which
postion the operator has selected with the flow selector
switch.
AUTO-OFF
When the throttle control switch is in the "AUTO-OFF"
position, the engine speed is held to maintain 5 gpm/19
lpm or 10 gpm/37.8 lpm depending on which position
12 ► GTR20 User Manual
Before starting the engine make sure the flow selector
switches are in the OFF position.
Note: The power unit will not start if the flow selector switches are not in the "OFF" position.
Turn the Ignition Switch to the START position. After the
engine starts, release the switch.
Gradually push in the choke knob as the engine begins
to idle smoothly.
Allow the engine to warm up.
Connect hoses and the tool as desrcribed on pages 7
and 8.
OPERATION
FOR 5 GPM OPERATION
For 5 gpm operation, select mode of operation with the
Throttle Control switch, either auto-idle-on or the autoidle-off position. Move the flow selector switch to the 5
gpm position.
SHUTDOWN
1. Ensure the flow selector switches are in the OFF position (center position).
2. Unless already at idle the power unit should return
to idle. This may take a few seconds for the unit to react
due to a built-in program delay.
Note:
If operating both 5 gpm circuits move both flow selector switches to the 5 gpm position. Both 5 gpm
circuits are independent from each other and can be
operated on its own.
3. Allow the engine to idle for approximately one minute
and move the Ignition Switch to the OFF position.
When finished operating the tool, move one or both flow
selector switches to the OFF position.
FOR 10 GPM OPERATION
For 10 gpm operation, select mode of operation with the
Throttle Control Switch, either auto-idle-on or the autoidle-off position. Move both flow selector switches to the
10 gpm position.
When finished operating the tool, move both flow selector switches to the OFF position.
Note:
Either set of couplers can be used for the 10 gpm circuit,
but DO NOT use two separate tools when in the 10 gpm
operation mode.
COLD WEATHER STARTUP
1. Use the procedures described under "STARTUP"
and then follow the procedure below.
2. Hydraulic fluids are thicker in cold weather. Therefore, it is recommended that the engine be run at low
idle long enough to bring the fluid temperature up to a
minimum of 50°F/10°C.
3. If the tools and tool hoses are cold, it is recommended to allow hydraulic fluid to circulate through the
tool hoses until warm before using the tool.

STORAGE
Follow the maintenance schedule and general maintenance instructions in the engine maintenance and operation manual furnished with the power unit.
• Clean the unit thoroughly before storage. Do not use
water pressure.
SPARK PLUG
• Always store the unit in a clean and dry facility.
On power units equipped with Briggs & Stratton Engines,
ONLY Champion RC12YC or equivalent can be used.
• If the unit will be stored for a prolonged period (over
30 days), add a fuel additive to the fuel tank to prevent
the fuel from gumming. Run engine for a short period to
circulate the additive.
For power units equipped with Honda Engines, ONLY
Denso J16CR-U or equivalent can be used.
Incorrect type spark plugs can produce radio frequency
interference that will corrupt and damage the controller.
Failure to use the correct spark plug could result in a
warranty that will not be considered.
HYDRAULIC SYSTEM MAINTENANCE
• Check hydraulic fluid level daily. Add fluid per specifications in this manual. (See "HYDRAULIC FLUID" under the section titled "OPERATING INSTRUCTIONS".
• Replace crankcase oil with new oil.
• Remove spark plugs and pour approximately 1 ounce
(30 ml) of engine oil into each cylinder. Replace spark
plugs and crank the engine slowly to distribute the oil.
• Check hydraulic reservoir for water. If water is found,
change the oil and circulate it through the tool hose and
tool. (See "HYDRAULIC SYSTEM MAINTENANCE"
earlier in this section).
• Remove condensed moisture from the hydraulic
fluid by pumping the hydraulic fluid into a 5 gal/20 l container through the pressure hose. Make sure the engine
is at idle when performing this procedure. When the hydraulic reservoir is empty turn the engine off immediately.
• Allow the fluid to sit long enough for the water to settle
to the bottom of the container. Slowly pour the fluid back
into the hydraulic tank, avoiding the water at the bottom
of the container.
• Each day, check hydraulic lines and fittings for leaks,
kinks, etc. Do not use your hand to perform this check.
• Change the hydraulic filter element every 200 hours
of operation. Change more often if cold, moist or dusty
conditions exist.
• Check oil cooler for debris. Remove debris with air
pressure.

• Disconnect tool hoses.
PROGRAMMABLE CONTROLLER
The Stanley programmable controller is an electronic
engine governor that provides a means of controlling
and limiting engine speed by adjusting the fuel control
lever with a proportional actuator.
The controller is factory preset and has no manual adjustments.
A flashing LED indicates
the fault condition
tion.
a. If actuator does not move it is defective. (Replace).
b. If actuator moves throttle to wide-open position, the
module is defective or there is a wiring problem. (Replace).
FAULT CODES
The Stanley controller is capable of identifying certain
fault conditions and alerting the user to them. A flashing LED indicates the fault conditions. The current fault
code list is shown on the following page. Please note
the following:
1. When power is first applied to the controller, the LED
will flash just once for one second to indicate that the
LED is working.
TROUBLESHOOTING GUIDELINES
Please follow the checklist below to troubleshoot your
Stanley controller.
1. Check battery voltage for stability and correct value.
The LED will turn on for one second when the controller
4500 is first powered up.
2. Check the actuator linkage for binding and backlash.
2. If there are multiple faults, the LED will flash them all in
sequence. Count the flash codes to determine the fault
conditions or connect the Calibration Tool to observe the
fault conditions. (Use the “Display Faults” option under
the Monitor Menu.)
3. If there are no faults, the LED will flash once at
reset and from then on indicate the detection of engine
speed. A continuous ON LED indicates that a valid
engine speed is being sensed.
4. The controller will attempt to shut down for some
faults and will not permit starting after reset with faults
1, 5 and 8.
CHECKING PERFORMANCE CONTROL™
(ELECTRONIC GOVERNOR-STATIC
CHECK)
To determine whether a governor problem is being
caused by the actuator or the control module, perform
the following static check exactly in order shown.
A pair of jumper wires and a known good 12-volt battery
is required.
1. Disconnect red and green wires from the control module to actuator.
2. Attach jumper wires from battery to RED and GREEN
wires to actuator.
a. Attach 12 volt + (positive) to RED wire.
b. Attach 12 volt – (negative) to GREEN wire.
3. Actuator should move throttle lever to wide open posiGTR20 User Manual ◄ 15

TESTING & TROUBLESHOOTING
GENERAL
Tests and adjustments should be performed periodically
to ensure the power unit is operating at maximum efficiency. Stanley Circuit Tester (part number 04182) is
recommended. This tester can be used to isolate problems in both the engine and hydraulic system prior to
any power unit disassembly.
TESTING THE HYDRAULIC CIRCUIT
The following tests can be performed to ensure that the
hydraulic pump is supplying the correct flow and pressure and that the system relief valve is operating properly.
During these tests, make sure the engine is warm and
operating smoothly. If test results are not as specified,
refer to the troubleshooting table in this section for possible causes.
9. At 2100-2200 psi/148-155 bar, the relief valve should begin to open. The pressure at which the relief valve just begins to open is commonly referred to as the "cracking pressure". At the "cracking pressure," the flow rate should start
to drop because the relief valve is allowing fluid to bypass to
the hydraulic reservoir. The "cracking pressure" is preset at
the factory and if it is not within the above range, the relief
valve must be re-set as follows:
a. The relief valve is located on the right side of the unit just
behind the dash panel. It putrudes out from the manifold assembly. Use a open end or box end wrench to loosen the nut
on the relief valve.
b. Use an Allen wrench to adjust the relief valve. Turn clockwise to raise the pressure and counterclockwise to reduce
the pressure.
c. Tighten the nut and retest.
TESTING THE 5 GPM OR 10 GPM CIRCUIT
To test the circuit, proceed as follows:
1. Set the flow selector switches to the OFF (center) position.
2. Set the throttle control switch to AUTO-OFF position.
3. Connect the Stanley Circuit Tester across two hose
ends (where the tool would normally be connected).
4. Fully open the tester restrictor valve (counterclockwise).
5. Start the engine and allow it to run until warm.
6. Switch the flow selector switch to 5 or 10 gpm depending on which flow you are testing.
7. With the engine at the programed speed, the test flow
gauge should read 4-6 gpm/15-23 lpm or 9-11 gpm/3441.6 lpm.
8. Slowly turn the restrictor valve clockwise while watching the pressure gauge. The flow rate should stay at 4-6
gpm/15-23 lpm or 9-11 gpm/34-41.6 lpm as the pressure
gauge reaches 2100-2200 psi/148-155 bar.

FUEL TANK & CAP
NOTE: When ordering a fuel tank (item 37)
or fuel tank cap (item 35) DO NOT MIX OLD
STYLE TANK AND CAP WITH NEW STYLE
TANK AND CAP.
If you have a power unit and it was purchased
prior to 2011 and need to replace the fuel tank or
fuel tank cap, you must purchase the same tank
and cap that came with your unit.
For example if you have a power unit prior to
2011 do not purchase a new style fuel tank, your
engine will not be equipped with a fuel vapor
fitting.
The old style fuel cap is a vented cap, while the
new style fuel cap is not a vented cap and venting is achieved thru the vapor line.
The old style fuel tank has only one fuel line
coming from the tank to the engine. The new
style fuel tank has two lines coming from the fuel
tank to the engine, one is the fuel line and the
other is a fuel vapor line.
